Nieman, A. (author)Determining the way to make a reclamation project with many excavation areas or borrow areas, and several pieces of dredging equipment at minimum costs takes too much time to do by hand. A linear programming application is made to support the allocation of excavation areas and pieces of equipment to reclamation areas. Such an application was...master thesis 2001

Verweij, J.F. (author)In 1984 en 1985 hebben proeven aangetoond dat het mogelijk is om dichtheidsstromen op te wekken van water met een hoog sedimentgehalte. Het onder lage druk (ca. 1 bar) injecteren van water in de bodem, het zogenaamde 'jetten' verdunt de bodem tot een water-sedimentmengsel. Door het verschil in dichtheid tussen het water-sedimentmengsel en het...master thesis 1997

Gerritsen, J.L.S. (author)Growing concern about global warming and climate change intensified the research into more efficient ways of operation in the maritime industry. These researches triggered the use of electrical batteries in hybrid systems. Van Oord aims to operate more efficiently, which implies using less fuel and thus emitting less carbon dioxide. A way to...master thesis 2016

Bruinsma, J. (author)De sleephopperzuiger "Volvox Terranova" is eigendom van Van Oord ACZ en heeft een laadcapaciteit van 20.000 m3. Na het walpersen van de lading blijft een restlading over van ca. ---m3. Het doel van dit onderzoek is een voorstel tot aanpassing van de "Volvox Terranova" te presenteren om de restlading te minimaliseren, zonder de leegzuigproductie...master thesis 2001

Onderwater, M. (author)People always want to live near water and all over the world the areas near the sea get more and more built with houses, hotels and infrastructure. For this reason there is a trend to reclaim land by making an artificial island near or against the existing coast. Examples are the airport 'Chek Lap Kok' in Hong Kong and the 'Plan Waterman', a...master thesis 1997

Van Aalderen, M.W. (author)Royal Boskalis Westminster nv is an international group with a leading position in the world market for dredging services. In most practical cases a jet installation or a big discharge aperture is used for the fast unloading of a load of sand. When a relative small discharge opening, without the use of a jet installation, is used to unload a...master thesis 2009

Vessies, W.C.N. (author)The Maasvlakte II project is a joint venture between Boskalis and Van Oord. During the construction, they have measured the relative density for different kind of work methods, by making cone penetration tests. The result of those measurement is, that the measured relative density for the Maasvlakte II project is higher than the values that can...master thesis 2012

Lubking, P. (author)Voor het optimaal beladen van een sleephopperzuiger is het van belang inzicht te hebben in de processen die plaatsvinden tijdens de belading. Een van de deelprocessen is de entrainment van lucht in de beun bij het inbrengen van het zandwatermengsel. Bij het storten is er namelijk vaak sprake van een plunging jet, een vallende waterstraal. Een...master thesis 2000

Schulting, W.H. (author)Waterinjectie baggeren (WIB) is een baggermethode die slechts vijftien jaar geleden is bedacht en ontwikkeld. Door middel van een patent is HAM nu nog steeds het enige baggerbedrijf dat deze winstgevende methode mag toepassen. Grote voordelen van de methode zijn de natuurlijke methode van transport door middel van zogeheten dichheidsstroming en...master thesis 1998

Bardoel, J.W.S. (author)Rijkswaterstaat is responsible for maintaining the fairway of the river Waal for navigation for more than a hundred years. In the past problem areas, which cause hindrance for navigation and block the fairway, were prevented with structural measures. Dredging was used as a last resort. In 2005 the desired fairway depth was increased from BRV -2...master thesis 2010

Radermacher, M. (author)Dredging and reclamation works are known to generate significant amounts of turbidity. In most coastal zones around the world, the resulting clouds of suspended fine sediment bring along environmental risks. Dredging contractors take mitigating measures to prevent free spreading of turbidity, which is usually also demanded by their clients and...master thesis 2013
